Introduction:Developed by the Microprocessor Standards Committee of the IEEE Computer Society.
First of all, IEEE 754-2019 replaces IEEE 754-2008.
This standard specifies interchange and arithmetic formats and methods for binary and decimal floating-point arithmetic in computer programming environments. This standard specifies exception conditions and their default handling. An implementation of a floating-point system conforming to this standard may be realized entirely in software, entirely in hardware, or in any combination of software and hardware.
Keywords: arithmetic, binary, computer, decimal, exponent, floating-point, format, IEEE 754, Minterchange, NaN, number, rounding, significand, subnormal.
1.2 Purpose:This standard provides a method for computation with floating-point numbers that will yield the same result whether the processing is done in hardware, software, or a combination of the two. The results of the computation will be identical, independent of implementation, given the same input data. Errors, and error conditions, in the mathematical processing will be reported in a consistent manner regardless of implementation.
